What is Metallography
Metallography is the study of microstructure, how it is produced by composition and processing control, and the relationship between microstructure, mechanical and physical properties, and performance or service behavior. To examine the microstructure, we must prepare specimens properly so that the true structure, free of artifacts due to preparation, can be observed and properly identified, measured and interpreted.
What is Microstructure
Microstructure is the structure of a suitably prepare specimen as revealed by a microscope Microstructure consists of phases and/or constituents.
A phase is a physically homogeneous, mechanically separable portion of a material system. A constituent is a phase or combination of phases, which occurs in a characteristic configuration in an alloy microstructure.
